We've also found that current mainline ICEs compiling the testcase with "-O0 -fschedule-insns -fschedule-insns2".

I suspect this is a bug in ia64_reorg in ia64.c. It shouldn't be trying to schedule during a non-optimizing compile. So the line if (ia64_flag_schedule_insns2) should be if (optimize && ia64_flag_schedule_insns2) That gives us the desired affect that -fschedule-insns2 only works when optimizing. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
